To all whom 'itmay concern: v v

Be it knownthat I, Rrcirsnn Gnrnsnn, a citizen of the United States,residingin New York, inthe county v`of N ewYprkf, borough of Manhattan,and'State-of/ New ments in Printing-PlateCliains, of.wh"cl{tli-followngis a's'pecification. Q. This inveiitionis Vforprodueingani'mprovedprinting -plate arid printingplate chinfor use in 'addressingmachilies, andtheplats of which may be readily assembledone withanotherwithoiit bending eithiof them, and when assembled land turnedslightly on' the connecting pintlesithey willbe locked fromdisassemblage,

and the pintles of which, plates are iormedl for reducing {rit-tion and`reinforced for 4 inivi-easing the stabilit/y of the chain.y

For addressing .xinachi-nes and similar purposes each addressis-forrnedfon plate generally by striking upV type faces from the faceofthe thin sheet metnlplate and such plates are articulated togetherinto a chain, which will be rollednp and as ,used will be unrolled androlled-opusit'is-unrolled. When-addressesare to be changed, eliminatedlrointhe list, orv new-ones'added, the c hainwill 'he separated at theappropriate place and plates added'or. removed as required and the.plates ,'desiredin suclfplatesis that they may be assembled ,anddisassenibled'when .in the proper positions easily and withoutbendingrlcither thc plates .or the'ir'hinge portions; iind also that'lupon being turnedslightly `from the positionoiasscinblage the plates-will besec'urely locked -togclhi-r andfthoir pifvotalaction willhefirecv 'anduneruruinhercd, and whenthe'platcs'aro subjected to strain .thehinge connections will be sti-ong enoughv to resistthc strain,particularly so 'when the :plates are turned'lar ,kpast'their normal,position and a position where their" stop' laces tend to preventfurther turning. l l l The pintles ofthe chains as now freqpentlyconstructed will Awhen the plates are turnedwith their incestow'ardeat-li other bend ,and upon'coiitinued strain spring ont of theirsockets, thus disconnecting one portion of the chain from theremainder.l But the present iinproverncnt so disposes the metal of thepintle portions thatjt not only is stiflened but reinforces tlle neckcarrying it, and the neck is so disposed relative to the plate that it`und the plate mutually reinforcceach other, the

. connection between the pintleland plate being stif encd and thel hingecarrying portion ofthe plate being strengthened. r K

. In the drawings accompanying and forming a part of this speciiication,`Figure l is a view of portieri of the chain looking at the printingfaces of the plates, which plates embody thepresent'improvoment. Fig. 2is an enlarged perspective view'showing portions oi twov l plates andillustrating the hingel members. Fig; 3 isl an end view oi a pair oisuch plates, enlarged to about double the size found convenient for use,in the position they will occupy whenbeing assembled 'one with "anotherand ybefore they have been turned into a locking position. Fig. 4 is anenlarged and broken off end `view of the hinge members of a pair ofplatesinlabout .the same relative positions asi-shownv in Fig. 3. Figs.5

and 6 are similar views respectively showing the plates turned into alocking position. Figs. 7 and B show a `position with `the bac'k` facesof the plates turn'ed at about right angles to each other. Figs. 9 and10 show the articulated plates in about the same plane; and Figs. l1 and12 show the plates turned with their printing' faces at an anglejone tothe other, and in which the limit of their relative angular movement'.

etI

' Inone of the views a number of plates 20 are illus#` i.,trated'articulated together for use, each' .plate having allangeportionl'21 along-one edge' curved toward the back face 22 and away fromthe printing face`23, upon which latter face suitabletype will beviorlned. The

edge v29 o the flange reaches toward the back-face 22 Near each end ofthe plate the Bange 21 is cut awayas at 24 for receiving the neck 25carried by the edge 4of a similarly formed plate and the necks carrypintles 26 for entrance' into the space ,27 of the curved flange. .Theseparts constitute the. hinge members for the plates. -v n v It will beseen that the neck 25 is sharply offset frein the plate as at,28, thatis, the neck is in a plane at an angle tothe plane of the plate. Thisreinforces lthe neck. The pintles and tlie end oi the neck are lungitudinally channelcllor curved on a line parallel with thc edge of theplate, which will stiften the pintles and the neck and furtherstrengthen the regionv of the plate 'carrying the neck.

By. reference to Fig. 2 it will be seen that the face 45 oi the pintlesis a segment of `a cylinder, as is also the interior face 55 of thecurved flange.v This-gives a strong conneptio'n and one offering butlittle friction-al.

rsistancein' use. Whentwo plates are bronghttogethcr `for assemblage,lsee Figs. 3 and 4; designated for convenience and 50 respectively,- thepintles 26 'of the plate 40 will be slid, not sprung, under the curledflange 21 of the plate 50. It will be seen that the edge 41 f the'flange 42 as it were of the pintles clears the edge 51 of the flange 21,and that the edge 43 will by a continuation ofthe' movement be caused topass under the edge 51, when theplates will `be assembled with the faces45 and 55 in working engage- ,ment, and a relative angular movementof'the plates will cause the iacejl to turn on the face 55, which willtakethe edge 43 past the edge 51 and place the hinge 70 position theplates are represented as having reached l members in e. positionfromwhich they cannot be disshown in Figs. 7 and 8 the back faces of thepla-tes are ai; about right angles to each other, and there is a con-Bidemble area. oibearing face presented of the portion 46 on 56 and 47on 57, giving a good bearing` and one which will prevent shocking of theplates; in fact even in the position of Figs. 'and 6 this bearing ateach side lpf the pintle portion is illustrated, In Figs. 9 and 10relatively large bearings are had between the portions 48 and 58 vInthis position the plates are as they will he when the 'chain of platesis nearly straight. Figs. 11 and l2 show the plates bent backwatdly fromthe assembling position and' until the face 49 has abnttcd the face 59,and such` engagement with the 'bearing between the portions 48 and 58prevents the further relative movement -of the plates. In each of Figs.4,- 6, 8, l and 12 only such reference characters have been .,applicd asare mentioned in the-description of such figures. This will avoid anunnecessary confusion of r reference characters.

Having thus described my invention, I claim as new: 1. A chnin foraddressingl machines embodying. a number ofpiates articulated togetherand each plate comprising n typerreceiving portion and a curved flangealong one edge. it having a number of notches, the 1,other dge having anumber of necks bent sharply ut an angle to the plane of the plate, andtongues projecting from the necks in a direction longitudinally of theplate und in n diiferent pinne from the plane of the necks.

2. A printing plate chain` comprisingn number of sheet metal platesarticulated together' and each plate hnvlng a flange-.portion curledover from its printing face along one edge, said iinnge having` :ininterruption near each cud oi' the plate, and said pluie also having :ipair of oii'sci sub stantlally tint necks for entering saidinterruptions of nu adjacent pinte, and longitudinally cui-vcd plnllcscarried by the necks for entrance within thc curled iiungc of saidadjacent plate.

4. A printing plate embodying n type or printing portion of plate likeformation having along unc edge n curled flange having its edge nearlyreaching th(` back iure of tho plaie and iransversely notched near cachcmi, und :it ille other edge having offset necks for entering thenotches on u similarly formed plate, and said necks having pintlcsstiliened by longitudinal channels for cnil-:lure bciwecn the iinngeedge and back face of said similarly formed plate.

5. A printing plate embodying n sheet metal body portion having pint'lesockets at one edge. und nt the other edge transversely disposed necksand longitudinally disposed pintles lcarried by the necks and formed ofsaid sheet metal und curved about their longitudlnul axis, disposing themetal of the pintle transversely of the metal of the necks. i

6. A printing plate embodying n sheet metal body portion' having plntiesockets at' one edge. and 4:it the other edge necks oifset nt nn tinglefrom said body, und plntles carried by the necks and curved about theirlongitudinal axis transversely ot the necks.
